convertSambaAccount doesn't handle machine accounts

[Brad Langhorst]

it leaves 
primarygroupid in there because
	if ( $entry->get_value( "primaryGroupID" ) ) {
return false when the value is 0

machine account have a 0 value in that field

this patch makes the ldif work with slapadd but i don't know what samba
will do with groups like
 S-1-5-21-AAAAAAAAA-NNNNNNNN-XXXXXXX-0

I also had to modify all the machine accounts to include the
objectClass: account
